4It/iy invention Vrelates to ard'oor.. jack.

An Object ofinyinventio'n is to provide a door jack for the purposeofrsecuring .a-1do;or.while.it.is beingV planed during the fitting ofsaid door to the door jamb structure.

A further object. oi/myfinve'ntion; ist to provide a door iaclklwhichcan be readily folded up to a verycompact form. sogthat it can betransportedV from-.place to Iplace thereby.` eliminating the needfor along, and cumbersome duorgjack.

A further object' of my invention is to provide adjustable features onthe door jack so that it can be accommodated to various doorthicknesses.

With these and other objects in view, my invention consists in theconstruction, arrangement, and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation of the door jack,

Figure 2 is a plan view of Figure 1,

Figure 3 is an enlarged sectional view taken along the lines 3 3 ofFigure 1,

Figure 4 is an enlarged sectional View taken along the lines 4-4 ofFigure 3,

Figure 5 is a detail,

Figure 6 is a plan view of the door jack in its collapsed or portableform, and

Figure 7 is a side elevation of Figure 6.

My invention contemplates the provision of a door jack which can beplaced upon the floor and wherein a door can be placed in the jack andplaned olf where required so that the door can be properly tted into itssurrounding structure or framework, and wherein the jack can becollapsed to a minimum mass for transporting the same.

I have used the character 10 to designate a section of the jack which ismade of a flat board, and formed in the member 10 is the groove 11.

Hinged at 12 to the member 11 is a further piece 13 of the same generalshape as the member 11 which also has a continuing groove 14 which is ofthe same configuration as the groove 11 and which groove extends to theend of the board piece 13. The members 10 and 13 include a series ofspaced blocks 15 attached therein (also see Figure 3), these blocksbeing adapted to rest upon the floor surface so that the restrictedareas thus provided will allow the jack to be moved along the oorwithout marring, and will allow readier movability, it being noted thatthese blocks 15 are so spaced that when the member 13 folds under themember 10, the blocks 15 in the member 13 will be positioned between thecorresponding blocks in the member 10 so that the device will foldneatly.

The groove 11 extends to the abutment portion or shoulder 16 (see Figure4) and hinged at 17 adjacently to the portion 16 is an upwardlyextending flat post or abutment unit 18 which extends at a slight angleas rates Patenti@ ice shown in Figure 4, and which'includ'es avertically positioned 4further groove 19 which is in alignment with thegrooves 11 and' 14, the' groove 19 also including a cutaway portion. at20. which receives' the verticallyy posi-v tioned atstrip' 2'1 to whichis attached at 22'to suit'- able washers,V the spaced wing nuts-23 whichpass through slots 24', 'which slots 24` areprovided in the member 18,

movement of the strip 21 inwardlyv in.v the direction of4 the. arrow 25providingv means whereby varying thicknesses of doors 'canbe held withinthe groove'19."

Hinged; at 26 toone end of the memberA 10 is an angularly extendingbrace member 27 which `i`s also hinged at 28` to thefrear of thevertically positioned member 18', however, the hinge 26`includes aremovable liinge pin 29which is secured to a chain 30 which is attachedat' 31 to( the member 10,so that when the hinge pin 29v engag'ing hingemembers having a similar removableipiny such as- Jand`b`eing attached tofurther chains 30` which are attached at 31 to the various pieces asshown clearly in the various gures. Also hinged at 36 to the members 34are the further braces 37, the hinges 36 also including the hinge pins29 allowing removal thereof and the same type of chains as described.

The braces 37 are hinged at 38 to the small ears 39 which ears arepivotally secured by means of suitable screws 40 to the brace member 27.

Figures l and 2 show the jack in its normal operating position, and inuse one edge of the door, which is indicated by the dotted linescharacter 41, is placed in the grooves 14, 11 and 19 as clearly shown inFigure l, it being noted that the door will abut against the abutmentportion 16, and an upper point on the member 18, due to the slightangularity of the member 18, whereby the door is thus contacted at onlytwo points at the top thereof, which in eifect secures the door andeliminates marring of the door at the upper edge.

It will be Iobvious that an edge of the door can thus be convenientlyplaned, with the door thus being held rigidly until the surfaces willfit within the frame properly. Either edge of the door can be thusseated in the grooves for the planing operation, the function of themovable strip 21 being already explained hereinabove whereby doors ofvarying thicknesses can be accommodated.

Since the jack is relatively large in its expanded and operatingposition, it is important to collapse the same to a minimum size, whichI shall now explain. It should rst be observed that the removable pin 29is used in a variety of locations such as at the hinge 26, at the hingejoints 35, and at the hinge joints 36, Figure 5 clearly showing howthese hinge joints are made, one of the parts of the hinge interlockingwith the other parts, for instance, as shown in Figure 5, the hinge at36 including one hinge flap attached to the member 34 and the other tothe brace 37, this structure therefore being provided wherever theremovable pins 29 are used. In collapsing the arrangement, first, all ofthe hinge pins 29 are removed from the hinges 26, 36, and 35, and next,the piece 13 is folded at the hinge 12 beneath the piece 10, and thenthe piece 18 is folded downwardly against the piece 10, and next, thebraces 37 are pivoted inwardly on the pivoting points 40 where they willlie directly against each other, and next, the outspread legs 34 arefolded inwardly against the side of the entire arrangement, and then anytype of straps 42 are strapped about the arrangement as clearly shown inFigures 6 and 'I invention with various other advantages being readilyapparent.

Some changes may be made in the construction and arangement of the partsof my invention without departing from the real spirit and purpose of myinvention, and it is my intention to cover by my claims any modied formsof structure or use o'f mechanical equivalents which may be reasonablyincluded within their scope.

I claim as my invention:

A door jack comprising a horizontally positioned base member having alongitudinal groove therein for receiving a side edge of a door, asubstantially vertically positioned member attached to said base memberand having a further groove therein substantially in alignment with saidgroove, said substantially vertically positioned member being slightlypitched from the vertical, and further including a laterally movablestrip for accommodating varied door thicknesses, said horizontallypositioned member including a pair of mutually pivoted sections wherebysaid sections can be folded together, said sections includzontallypositioned member including laterally positioned legs hinged thereto,said laterally positioned legs including further hinge portionsincluding further hinge pins whereby removal of said further hinge pinswill allow folding of said legs inwardly, further normally angularlypositioned braces pivoted to said brace, and removably hinged to saidlaterally positioned legs and including still further hinge pins at thehinging points thereof, said further normally angularly positionedbraces being pivotally secured toward the upper end of said bracewhereby said angularly positioned braces can be folded inwardly afterremoval of said still further hinge pins.
